Source Audio Atlas Compressor
Studio-quality parallel compression in a smaller enclosure! If you know Barber Electronics, you know it's all killer no filler. Excellent condition, with box, ships fast and safe.
"A Class-A discrete mixer circuit blends the dry signal in with your compressed signal, bringing some attack and clarity back into your tone, even with heavy compression. Two additional switches to your standard guitar compressor controls give you a faster action for quicker picking and more percussive playing, and a brilliance switch to add just a touch of beautiful high-frequency air to the party."
